Application filed July 12,1901. Serial No. 68,052. (Nopiodeld Be it known that we, ARTHUR JAMES PUR' sALL, wax-candle manufacturer, residing at 272 Victoria'road, Aston, and HERBERT DAVID JACKSON, chartered accountant; --re-. siding at 48 Cherry street, Birmingham, Eng- 7 the King of Great Britain, have invented certain new. and useful Improvementsin VVax-BurningLampspfwhich thefollowing is a specification.

This invention has relationto cycle, care riage, and otherlamps inqwhich wax' is'u'sed as the illuminant; and it consists, in'the first part,ipanew orimproved construction of wax burninglamp,and,in.the second part, in a wax burner and supply attachmentadapted'for use in connection with any form of lamp.

Figure 1 of the accompanyingdrawings rep-- resents a fullvertical section of a cycle-lamp; designed for burning wax and constructed e form of our invention. Fig. 2 is a horizontal section of Fig. 1 upon the dottedline'gr, I Fig. 3 is a View showing the wax reservoir-and burner parts of the lamp separated, the former being shown in front elevation and the latter in transverse vertical section. Fig. 4 is a vertical section of the wax reservoir and burner parts adapted and applied to a carriage-lamp and so constructed as to bebodily detachable or removable from the interiorthereof, and Fig. 5 is a horizontal section of Fig. 4 upon the dotted line 00'. p The same letters of reference indicate corresponding parts in the said figures.

The body a of the said lamp may be of any suitable construction, and in the form represented it is of a cylindrical form and is procowl a, a suitably-glazed bell or front a and a detachable or removable bottom or base a carrying the burner, while provision is made for supplying the interior with air through suitahle-piercin gs or perforations.

The lamp as a whole ma a spring-back Z), of any a tion; but we do not limit these details, of any type.

Disposed at and base a is awax-r y be supported by pproved construcourselves to any of as the body of the lamp may be attached to the back of the eservoir 0, arranged to slide .the bottom 05 this wax-r the burner (1, consisting into' 'and out of a recess or chamber a, provided for its receptionin the back of the body part and secured in place in any suitable manner. The said reservoir isope'n atthe top, end cf, and may be provided with ahinged' lido'rYi-emovable part to enable it to be refilled or charged with wax whenits' contents are exhausted, and is preferablymade in the form of.a flat boxof Fconsiderable area at the front; bn'tthe dist-auceor depth between the front and baelcis only small. 'Forward 0" eserv'oi r we arrange: of a small chamber 01, also containing wax and provided with a screwed pn cap or cover (1 for retaining the wax in theburner-cham be r, which is arranged closetothe front of the reservoircandis in communication therewith through a small- I bore pipeor passage e. \Vithin the burner and projecting through the central hole Z in the cover thereof is anindestructible wick f, ni'adeof'asbestos or the. like and supported 1 by "an, encircling spiral spring 9 or equivalent skeleton carrier, secu red to a small base-plate g, resting'on thebottom of the chamber, with I both the lower part of the wick audits carrier.- spring being embedded in the wax. By this. construction whenthe Wick is lighted'the wax in the bu rner-chamber-isinst-consumed, and

the-heat thus generated melts the wax in the Y adjacent reservoir, which-passes through the 'pipe connection to the burner and keeps up the supply to the wick until the whole of the wax within the influence of the heat of the flame has been consumed, when the reservoir with burner may be readily removed from the lamp and recharged witha refill cake of wax, which said cakes may be specially prepared in a form and size suitable for the pur- 9o pose. The front of the reservoir v may be formed asa reflector h, while the burner part may be adapted to contain two, three,or other number of suitably-supported wicks.

Our invention may be applied to carriage 5 and other lamps in a similar manner, with 'the wax-reservoir being so disposed relative to the burner (which may be provided with any number of wicks) that the whole of the contents are subjected to the int! uence of the roe heat radiated from the fiain'e' or flames of the burner, thus keeping up the supply of mola door by which access is obtained to the in terior. j is the wax-reservoir, (the front of which may be concaved and polished to form a reflector,) having an open top j for recharg ing purposes, while is is the burner, connected with and supported immediately in front of the said wax-reservoir by an arm I, with a passage Z, through which molten wax flows 1 from thereservoir tothe burner-chamber r when liquefied by the heat radiated from the flame of the bu rner-wick. The reservoir and burner may be mounted upon a tray or slide, such as m, fitting into the bottom of the lamp and adapted to he slid bodily into and out of position therein. We do not, however, confine ourselves to any particular method of mounting or arranging the wax-reservoir and burner, so long as they are in such proximity relative to one another when in-position for use that the heat from the flame will keep the wax iu the reservoir in a molten state, and eflicieut provision is made for the flow of such molten wax to the burner chamber in which the wick or wicks is or are supported.

We propose in every case to provide the interior of the wax-reservoir with a perforated thin metal diaphragm f, which will prevent the chokiug of the passage from the reservoir to the burner-chamber by solid or unmelted wax, which being of higher specific gravity than the wax in a melted state tendsto fall to the bottom of the reservoir and obstruct the-outlet. The diaphragm is preferably placed in an upright position parallel to the front of the reservoir and extending from bottom to top thereof, so as to efliciently screen the outlet from the unmelted wax, while the molten material passes freely through the perforatious of the diaphragm to the partitionedoflf front of the reservoir and is kept in that ,condition by .the' heat trom the flame, which ese,741

affects the said front more than any other art.

p VVax-burning lamps constructed in accordance with our invention may be readily adapted for use as table, wall, or hand lamps, as

well as to cycle and carriage lamps, as described.

According to the second part of our inven tion we construct a wax-burning attachment which may be readily applied to existing lamps and consisting of a wax-reservoir and a single or multiple wick chamber connected together'by a pipe or passage and disposed in such relationship that the supply of wax to the burner is kept up by the heat generated by the burner-flame. This attachment is substantially the same in construction as the removable burner and reservoir of' the lamps represented in the drawings described above and may be provided with hooks, clips, or other means for keeping it in place within or upon the lamp to which it is applied.

Having fully described our invention, what we desire to claim and secure by Letters Patout is- A wax-lamp comprising a body, a base removable therefrom, a reservoir, a perforated vertically-disposed diaphragm in said reservoir forming two compartments, one of which is designedfor the reception of a wax cake and the other of which has a passage leading therefrom, and a burner located below, and in proximity to said reservoir, and comprising a burner-receptacle into which said passage leads and a wick extending down to a point adjacent to the lower end of said receptacle, the said reservoir and burner being carried by said base and adapted to be removed from said body therewith.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
